No problems , I am happy to answer all questions . My first detector was a Garrett Deep-seeker that I used on Balmoral beach before 1 and 2 dollar coins . It had 6 - 9 volt batteries , so cost a fortune to run . It was made for detecting gold .
As far as I know there is no license needed to detect on beaches in Australia . In the U.K. there is a lot more problems , read about some guys that found a lot of old treasure but they did not declare it . They are now in jail for 5 or more years .
The Explorer is not suitable for finding gold . It does not have the correct frequency for locating gold . Other people will advise you on which one to start with on this forum .
It is no longer easy to find coins on the beach as there are many people with detectors . Also people are using less coins , it is all tap and go . I was down on the beach because it had been washed away with big seas . If you see black sand , go with that as the coins are in the black sand . Black sand is a heavy mineral that they used to mine on Fraser Island .
To find gold or coins it is not easy and takes a lot of time . Concentrate on coins for the time being and look at gold later .
Look where people are sitting on the beach , that is the best place to try . People sun baking up near the dunes etc .
Go to U-tube and see how people get coins out of parks . It is not easy but that could be you best return . You need to know or think about were people would sit ,under trees etc . You have to try and out think all the other detector operators .
